Last week I was trying to find out why are the level 56 arcane weapons so rare.
I found out that they are so rare because they were only lootable from locks during Ursoth event 4-5 years ago.
The ursoth event chest which contains them is no longer exist in AL, and if there are some of these crates, I doubt there are more than just a few.

All other arcane weapons in the game are lootable from different locks which players are able to get so why the level 56 arcanes are only bound to an event from 4-5 years ago?

I believe all old arcane weapons shouldn't be too hard to get.
Any thoughts?
